Description

2,2',3,5,6-Pentachlorobiphenyl CAS NO 73575-56-1 is a specific, high-purity congener of polychlorinated biphenyl (PCB), a class of synthetic organic chemicals. This compound is of significant importance as a certified reference material and analytical standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily needed by analytical laboratories, research institutions, and environmental agencies involved in the precise quantification and study of persistent organic pollutants (POPs) in various matrices.

Application

• Certified Reference Standard for the calibration of analytical instruments (GC, GC-MS, HPLC) in environmental testing.
• Analytical Method Development and Validation for the detection and quantification of PCB congeners in complex samples.
• Environmental Fate and Toxicology Studies to understand the behavior, bioaccumulation, and toxic effects of specific PCB congeners.
• Quality Control/Quality Assurance (QC/QA) in laboratories performing compliance testing for regulations like the Stockholm Convention on POPs.
• Research Chemical for academic and industrial studies on the chemistry and environmental impact of halogenated aromatics.
• Spiking Solution Component for preparing laboratory control samples to assess analytical recovery and accuracy.

Quality Control

Our high-purity 2,2',3,5,6-Pentachlorobiphenyl is produced and handled under strict quality protocols to ensure identity, purity, and stability for critical analytical applications. Each batch is characterized using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, congener-specific identity confirmation, and solvent content (if applicable) is provided to guarantee traceability and compliance with research and regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place, preferably at controlled room temperature (15-25°C). For long-term stability, storage under inert atmosphere (e.g., nitrogen) in a freezer (-20°C) is recommended. Keep away from heat and open flame.
